Okay, that's great, thank you to the both of you! I can put together a sufficient answer with all of that info. Thanks again.

Where is the best location for a light bulb filament to be placed in a spotlight, when using a concave mirror? It makes the most sense to put it at the focal point of the mirror if you want parallel light beams but are you supposed to have parallel light beams when you use a spotlight? Or do...

I'm really not understanding this at all, thanks though! I guess i'll just leave it.

the velocity is equal to 1.4m/s and the force acting upon the bob is gravity... but don't i need to know the mass of the bob in order to figure out the force of gravity? still not sure where to go with it..

The pendulum bob in the above figure must circle the rod interrupting its swing, and the string must remain taut at the top of the swing. How far up must the bob be raised before releasing it to accomplish these goals? I don't know where to begin with this because I don't quite understand...

It's a simulation, everything can be altered so there isn't really a question to post. And I can't post the link to it because it's an internal website.

hmm.. I just don't know what it could be.. there's Fn, Fa, Ff, Fg all in the question but I don't know where the Fd comes from.. maybe Fdown?

I'm trying to calculate the acceleration of an object but first I need to calculate the net force. For this question we were told Fnet = Fa-Fd-Ff.. just wondering what Fd is? Thank you in advance.

Oh okay, thank you to the both of you, you've been very helpful :)

So to maintain the scale at a constant force, you mean apply pressure to the scale myself, sit the baby on it and let go so that the baby would accelerate?

A spring balance cannot be used to measure the weight of anything under the conditions of a space shuttle. Is there any way you might use a spring balance to compare the 'heaviness' of twin babies born on the shuttle? Discuss. I don't know how you'd use a spring balance in the shuttle.. Any...

Yes, the previous posts helped solve it. I had the answer to start with but because of how the answer key showed the answer I didn't think mine was right.

Ohhh okay, I didn't think of that, thank you all for your help!

Two horses on opposite sides of a narrow stream are pulling a barge along the stream. Each horse pulls with a force of 720N. The ropes from the horses meet at a common point on the front of the barge. What is the resultant force exerted by the two horses if the angle between the rope is 60o...

Nevermind, I've figured it out now.. thank you
